Would you like to give it a try?
This feature caught my interest and I wanted to investigate a bit :) tmpfs defaults to half of the available RAM, with the 'size=' option to the mount command we can increase this limit but I believe that the upper bound is the sum of the available RAM + swap space. Would it be worthwhile to allow for the container filesystem to be stored in a non-temporary filesystem, for example allowing the user to specify the parent directory of the container root? This would let the container fs grow as large as the computer storage allows. -Robert
